The calculation comes to this: 
Let A be — 7.210 X 10°, 8 = 2.1563 X 2890, «, and a, the values 
of /, corresponding to 4, and 2,, f an unknown factor dependent 
on the unities in which J, has been measured. Then the following 
equations hold: 
(6) 
When we choose the values of 4 so that A, = 24,, and when

we put 1 = 2, we easily get:

The root x=1 yields 7 =o, has therefore no physical meaning, 
so that we find 7’ from:
